XBee is good; Synapse is just better. More I/O, embedded python, and generally better range at comparable cost! This particular module is 2.4GHz with OTA (Over-The-Air) speeds up to 2Mbps, maximum 450M (1500') range and a chip antenna for compact installation.
No doubt about XBee - proven, solid and robust. But Synapse modules are that much better! These small, low-power, transceiver modules, commonly run in the 915MHz & 2.4GHz spectrums, have a maximum extended range of up to three miles LOS (Line-Of-Sight) and the lowest power consumption in the industry. These RF Engines come pre-loaded with the SNAP® network operating system which allows the nodes to be natively mesh networked. Typical applications include wireless serial port(s), sensor monitoring, actuator control, or an intelligent embedded controller - the possibilities are limitless. Synapse takes 802.15.4 Zigbee/XBee style communication one step further, and makes it smart.
This particular RF module includes a user programmable (via python-based scripts), embedded ATmega128RFA1 microcontroller that can be programmed for all kinds of applications including remote sensor monitoring, or peripheral activation.
Other notable features include:
